19 Claims.

This invention relates to calculating machines and is concerned more particularly with an improved safeguard printing control means therein.

Calculating machines are frequently used for filling in on check forms the amounts of the checks. The machine may alsoeither calculate the amounts of the checks or/and accumulate a total of the amounts of checks filled in by the machine. In printing the amounts of the checks on the check forms, so-called safeguard symbols or characters should be printed to the left of the figures representing the amounts in order to render difficult any fraudulent alterations of the amounts thus printed on the check forms. However, it is also frequently desirable that such calculating machines should be capable of being used for other work as, for example, printing of amounts and totals of successive series of amounts without printing to the left of such amount un-, necessary symbols or characters which would render the printed amounts less easy to read and might cause confusion. Particularly in the case of calculating machines having traveling paper carriages and used for filling in amounts on check forms and concurrently producing business records of data relating to the issuance of checks on which the amounts are thus filled in, it is desirable that safeguard symbols or characters be printed to the left of the amounts when the latter are printed On the check forms but that no unnecessary characters be printed to the left of the amounts when the latter are printed on the ledger, journal or other record papers.

In prior machines provided with means for controlling the printing of safeguard symbols, such safeguard symbol printing control means have been more or less complicated and more or less limited in their adaptabilities to various kinds of work.

It is an object of the present invention to provide a calculating machine with an improved safeguard printing control means of relatively simple and inexpensive construction.

It is a further object of the inventionto provide a calculating machine with a safeguard printing control means of relatively easy manufacture and assembly so arranged in the machine as to be readily accessible for inspection, adjustment, alteration and/ or repair.

It is a further object of the invention to proing control means of such construction and operation as to eliminate interference between the safeguard printing control and other functions of the machine.

A preferred embodiment of the invention is i1- lustrated in the accompanying drawings, in.

Each amount key' 40; when depressed} rocksan individual detent' member which cooperates with theremainder of the usual key latching mechanism (not shown). The 'detent 4 I i'o'r: each-amountkey except' the 9 key in each bank is connected with the rearward upper end oi' "a stop -wire: 4z; the forward: end of whichixisrbentintona hook. shape and guided in 7 the. appropriate ;one ;of3.a': serleszof eightislotsrin eachrofsazpair off the usual :comb: plates 43 for the: respective;- banksof keys so that,.: when": an amount-keyiisa depressed; the transverse portion otz'thectozwardxhooked .endmf; the corresponding stop wire 42 is moved rearwardly into the path of a shoulder (not shown) on the usual actuator sector 45 for the corresponding bank or numerical order of the machine. Each actuator sector 45 is carried by the forward arm of the respective one of a series of levers 46 pivoted on the shaft 41 and'urged clockwise by the usual spring 48.

The amount-entering cycle of machine operatiorrzare initiated by depressions or one 01 the motor bars, such as M and U. During the forward stroke of the machine cycle a cam slotted plate 58 secured on the 800 shaft rock counterclockwise' with the latter and imparts a clockwise motion to a bail 52 whose side arms are -pivoted. onthe'shaft' 41, one of the side arms of said' bailcarrying-a roller 5! engaging in the cam slot in the plate 50. The cross member of thezzbaiL52-extends transversely beneath the forward .arms of all of the levers 46, normally holding them in their normal positions of Figs. 1 and 2 i ata-the counterclockwise extremities of. their strokes. As.= the .bail52 is rockedclockwiseduringrthe: forward'wstroke. of the machine;.cycle,, it permitseachlever 46 and sector 45 to move clockwise .unless; stopped by the usual zero stop- (not shown). or-until stopped by-v engagement of" the shoulder onv theesector-with. the stop:wire 42:01! a depressed-key 40 in a bank where a key 4|! for any digitfrom 1?'-to'8 has been depressed, or

The rearward rarm of each. lever .46 carries a series {of type 55 for the numerals iromfO" to 19" arranged thereon; so that, when the bail has reached the, limit of its: clockwise movement during-the iorwardistroke of-:the. machine. cycle and the. .actuatoresectors. 45. and levers 46 have been arrestedby. the zerostops, thestoprwiresfl or the bail 5?. in the positionsacorresponding to. the amount, set. up :onthey keyboard ofxthe machine, theity-pe 55ior, printing such amount will berpositionedalongthe: printing line of. a platen 56 carried. bya traveling paper. carriage..5| which is laterally movably mountedon a. raceway 58. at therear. of: theimachine. After the type 55 cor responding to-v the amount setup, on the keys 740 have thus: been positioned at theprinting line, they aredrivenr against the platen by the usual printin hammers, .60.- pivoted on:' the shaft 6 I The .usual: ink ribbon. .(notshown) inks 1 the, impression made by, thetype whereby the amount is printed on the-paper supported: onthe platen. The lateral movements of the carriage are effected by: carriage :tabulatingand return mechanisms substantially as disclosed in Rinsche Patent 1,580,534.-

During: the 'return' stroke, of the-machine cycle the bail :52 is returned. counterclockwise to its normal position of Figs. 1 and 2 by the .camx5fl secured to .the :shaft; and thelevers' 46 with the printing type .55 anduactuator sectors 45 :are correspondingly:retunnedrto their normal positions. Prior to :such.-return movement .of the actuator sectors :45rin an amount entering machine cycle, ,anxadde'subtract; totalizer .651(Fig, 1) or cross-footer; and/orione of a series ofxregisters 66 may. be meshed :with' the actuator 'racks to efiect the: entryof :theramountc therein "during the return of the actuator-sectorsto normal. The con structionzandoperationaof the add-subtract crossfooter-E5 and of the'multiple registers li6 may be substantialiyxas :disclosedx in Pasinskii Patents governed either by the paper carriage or in part by the usual total and subtotal keys 6! and 68 in a total-taking or subtotal-taking machine cycle. The crossfooter 65 or register 66 from which the total or subtotal is to be taken is engaged with the actuators 45 prior to their descent in the forward stroke of the machine cycle, the zero stops for the actuator sectors being disabled to permit such movement of the actuator sectors, which then are arrested in positions determined by the extent to which the register or crossfooter pinions are permitted to rotate before they are stopped in their positions. The printing type 55 corresponding to the amount thus withdrawn from the crossfooter or register are thereby positioned along the printing line of the platen prior to the firing of the hammers 60 near the end of the forward stroke of th total-taking or subtotal-taking machine cycle. The crossfooter or totalizer pinions from which the total or subtotal is taken are disengaged from the actuators prior to the return movement of the latter in a totaltaking cycle to leave the pinions in their 0 positions, but are permitted to remain engaged with said actuators during the return stroke of the subtotal-taking cycle whereby the amount withdrawn is again returned to the crossfooter or register pinions.

In the Burroughs High Keyboard machine, as is well known, the levers 46 are normally positioned, while the machine is at rest, so that the 0 type are positioned a step below the printing line of the platen and. during the forward stroke of the machine cycle, the levers 46 must follow the bail 52 through one step of movement to bring the 0 type at the printing line before moving any of the actuator sectors 45 below their normal positions. The connections between the levers 46 and the corresponding sectors 45 are, as is well known, stud-and-slot connections, permitting such a step of relative movement between each lever 46 and the corresponding actuator 45 for the purpose of permitting each actuator, for tens-transfer purposes, to move one step upwardly above its normal 0 position at the end of the return stroke of an amount-entering machine cycle.

Each printing hammer 66 is formed with a cam slot 16 in which is engaged a stud H on a firing member 12 pivoted on a shaft 13, the shafts 6| and 73 being supported in the two side frame members 75 of the printing mechanism. The firin member 12 is normally urged counterclockwise by a spring 16 connected at its lower end with said firing member. The firing member, however, is normally held in its position of Figs. 1 and 2 and against clockwise movement by a latch 11, pivoted on a shaft 1'! (Fig, 3) carried in the side frame members 15. The stud l I, therefore, normally holds the printing hammer 66 in its normal position of Figs. 1 and 2.

The upper end of th spring i6 is connected to a lower rearward arm of a pawl 18 pivoted on a rod 19 supported in the upper ends of a pair of arms 80 which are pivoted on a shaft 8! also supported in the side frames E of the printing mechanism. The arms 86 and rod l9 form a rigid bail which is urged counterclockwise by a spring 82' against a fixed stud I39. The rearward end of each pawl 18 has a hook shoulder 83 (Fig. 3) to engage a shoulder 84 on the upper edge of the firing member latch 11. Said pawl 18 also has a forwardly extending arm with a cam portion 85 to cooperate with a cam edge 86 on the lower side of the rearward arm of the lever 46 for'the corresponding numerical order.

The lower end of the left-hand arm 8!! extends below the shaft 8| into the path of a stud 8'! carried by a plate 88 secured on the 866 shaft so that, when the bail 52 reaches the limit of its clockwise stroke during the forward stroke of the machine cycle and the appropriate type have been positioned along the printing line of the platen, the stud 81 engages the lower end of the armand causes the rod '59 to be swung forwardly. The lever 46 for any bank of amount keys 40 in which no key has been depressed in an amount-entering cycle, or which is meshed with a crossfooter or register pinion already standing at 0 at the beginning of a total-taking or subtotal-taking cycle, will thus .be arrested in the position where the 0 type on the rear end thereof is at the printing line. When the rod 19 is rocked forwardly, the cam portion 36 of the under edge of the rear arm of any lever 46 arrested in the 0 position will be engaged by the portion 85 of the pawl T8 for the corresponding order and will rock said pawl clockwise before the latter .has moved sufiiciently forwardly to engage the shoulder 84 on the latch all so that said latch will not be tripped by the pawl 16 during the further forward movement of the rod i9. However, in any order where the lever 46 has moved beyond its 0 position, the hooked rear end of the pawl 18 will engage the shoulder 84 of the latch ll and rock the latter about the shaft ll to release the firing member 12 which is then rocked counterclockwise 'by'its spring 76 whereby its stud H swings the corresponding printing hammer E5 counterclockwise.

The lower ends of the cam slots 76 in the printing hammers 56 are enlarged in such a manner that the positive drive of the printing hammer by the stud H on its firing member ceases just before the printing hammer actually strikes the type so that the driving of the type toward the platen to eifect the actual printing impression is effected not by a positive drive from the firing member, but rather by the momentum of the hammer. 7 Each latch member ll except any one which is immediately to the left of a split in the printing mechanism has a laterally bent tail 96 which overlaps a straight tail 9| of the latch member l! in the next lower order to the right, so that if any latch ll is rocked by its pawl '18 to cause the printing of a digit from 1 to 9, the latch 77 in any lower order in which a 0 type is positioned at the printing line will be rocked by the next high-er latch ii to cause the "0 to be printed.

During the return stroke of the machine cycle, as the 800 shaft'returns clockwise to its normal position, a link connected at one end to the plate 88 and at its other end to a side arm of a bail 96 pivoted on the shaft 13 rocks said bail 96 clockwise to cause a cross rod of said bail to engage the forward arms of the operated firing members 12 and return such firing members clockwise to their normal positions in latched engagement with the latches Tl, the rod 19 carrying the pawls 78 being also returned rearward to normal position by its spring 82.

Safeguard printing For safeguard printing purposes, safeguard character type 100 are positioned on the rear ends of the levers 46 in those orders in which it is desired to print safeguard characters. In the particular construction illustrated, byway of example,- imthes accompanyingzdrawings; ;type' are positioned abovetthe regular0" type.=dnfthe= tens and hundreds: of: dollars:orderspand an extra 0 type is positionedabovatlie regulaK' fO type inthefdollarsuorder. .Meanszare -.also" provided which, inany safeguard printing operation oftthe machine,twill, just prior to the fir-ingot the printingihammers lillyreturn the levers T46 to their' normal positions with their regular 0 -type,-one-' step .belowthe printing line :of 'theplaten 'inrpat least one :order higher: than .the highest. order of the: amount to 'beprinted, providedxthat the number of orders in the" amount fdOGS" not exceed four.

and it will-also be'noted that Figs. 4,:,5:iand 6 show therear end of thelever dfi'for'thetnext higher (sixth) order'with digit type thereon, but, ashas been mentioned previously, it is desirable that-the machine shall be usable forrother than safeguard printing work and: that, in such .other work, it. may be necessary to print amounts 501'- figures of more than four numerical orders. However, it will be apparent that th safeguard printingprovisions may be applied. to any desired number of orders of the machine to pemnit the printing of safeguard characters .to the left :of amounts of any desired number of numerical orders. It safeguard charactertype areiprovided only. in those orders where required-to permit theprinting: orsafeg-uardcharacters to the left of the largest amounts intended. to :be printedin safeguard printing operations, the absence of asafeguard character: at the left of the amount printed bythemachine on: any. check or other paper where-safeguard printing wouldabe required-will help todirect attention to the ques-' tion of whether thewamount of the check or other paper;is incexcessof any which the machine operator is authorized to issue.

Means are also-provided, as will hereinafter 0e described to effect, in safeguard printing operations, the firingof the printing hammer in the next order-higher than the'highest order of the -amount'tobe printediin such safeguard printing operation.

The means for returning; appropriate ones .:of tre. levers- 48 to their normal positions prior to' the-firing ofthe printing hammers 60 in "safeguard printing operations comprises a series of pawls IIII pivotally supported on a shaft I02 (Fig 2) fixed in" a pair of arms'I03 pivoted ona shaft IMsupported infithe: printing mechanism side frame members'li.

Inzthe illustrated example there 'are five pawls I0 I each 'having' adepend ing arm I08; the lower: end of which is adapted to cooperate with aestud I09'on a'respective'one of the five lowestiorder levers 46. Each of the pawls has a rearwardly extending arm IIO having-on its upper and loweredgearespectively, two lugs- I II (Figs; 3 and 4) bent laterally'to the leftyas viewed from the front-of-th'e machine, and each ofsaid rearwardly extending arms- H 0 I except that of the iowest orderpawl IOI carries iii) a stud; H 2 :extending :to' the; right zbetwee'n the two-lateral lugs I II tofi -the1rnext.-iowemorderzpawl IOI.

Subsequently, but prior to the firing ofltheprintinghammers the stud'l06 moves on to step c of the cam edged! the" arm I03 andtherebydepresses the shaft I02 and pawls I OI'sufllciently to cause the pawls I 0|, whose depending arms I08 are vertically aligned with the studs I09 on their lovers, to depress the rear endslof such levers 46 and return such levers to their normal positions where the added safeguard printing type"100 on the rear ends of .such levers arepat the printing line of the platen at the time the printing hammers 60'are fired,

Figs. 3 and4 illustrate thepositions of the arts at the time the printing hammersSIl' are fired in' asafeguard printing operation when .thecharacters'correspondingf to an amount or ten centsare to be'printed. Itwill'be 'noted'tha't; because the added type on the units of dollars order lever 46 is a type, a 0 will be printed in the units of dollars order. Such arrangement is adopted when it is desired to print a 0 in the units of dollars order in any safeguard printing operation in which the amount to be printed is less than a dollar. When such an arrangement is adopted, it is desirable to print character immediately to the left of the 0 in the units of dollars order. It is also desirable to print a 0" in the tens of cents order if, in any case, the amount to be printed is less than ten cents. For these purposes, a small pin I 20 projects from the right end of the stud II2 on the tens of cents order pawl I0! through the rearward arm H0 of the units of cents order pawl IQI whereby these two lowest order pawls IOI are pinned together to rock as a unit on the shaft I52. Also, the rearward arm I I0 of the tens of cents order pawl IOI has at its rear end a leftwardly bent projection I2I which is positioned under a rearward extension I22 of the rear arm H0 of the tens of dollars order pawl IOI. While the parts are in their normal positions with the machine at rest.

there is sufficient clearance between the projec-' tion I2! and extension I22 to permit the tens of dollars order pawl IOI to be rocked during a machine operation sufficiently to place the lower end of its downward arm I08 above the stud 5! on the tens of dollars order lever 46 while the pawls Iill for the two lowest orders are held against counterclockwise rotation by the stud I09 on either of the two lowest order levers 46 being positioned in front of the depending arms I08 of either of said two lowest order pawls ISL Thus, whenever an amount less than one doL lar is to be printed, either one or the othe of the two 0 types on the units of dollars order lever 45 will be positioned at the printing line and the pawl IOI for the tens of dollars order will be positioned above the stud I09 on the lever 43 for that order and will, prior to the firing of the printing hammers, return the rear end of said lever downwardly to its normal position to place the 58 type thereon at the printing line.

The relative positions of the pawls IOI when an amount of one dollar or more, but less than ten dollars, is to be printed, is illustrated in Fig. 6. In such a case, the stud I09 on the units of dollars order lever 45 will be elevated sufficiently prior to the movement of thestud I06 onto the middle cam surface I) on the arm I03 to prevent forward movement of the depending arm I08 of the pawl I0! in the units of dollars order, and the latter pawl will permit only sufficient forward movement of the depending arm I08 of the tens of dollars order pawl IN to position the lower end of said arm I08 above the stud I 09 on the tens of dollars order lever 46.

The positions of the pawls in an operation for printing an amount of ten dollars or more, but less than one hundred dollars, are shown in Fig. '7.

It has already been explained that the rear end of any lever 45 which does not move above its regular 0 printing position will, by reason of its cam edge 80, rock the pawl 10 for the corresponding order, as the shaft I9 on which said pawl is pivoted is moved forwardly, to prevent the hooked rear end of said pawl I8 from engaging the shoulder 84 on the firing member latch ii and tripping the latter during the printing operation. However, as also previously mentioned, it is necessary to fire the printing hammer 00 for an order higher than the highest order of the amount to be printed to effect the printing of a safeguard character $3 With the particular arrangement above described, the printing of a is required in the tens of dollars order when printing any amount less than ten dollars, and a must be printed in the hundreds of dollars order when printing any amount of ten dollars or more, but less than one hundred dollars. For this purpose, the lower edges of the forward ends of the pa-wls I8 in'the tens oiv dollars and hundreds of dollars orders are formed with shoulders I25. When either of the levers 46 in the tens of dollars and hundreds of dollars orders is restored to its normal or safeguard character printing position by the pawl II for that'order, the pawl 73, as its shaft 19 is moved forwardly, will be rocked further clockwise than would be the case if the lever do for that order were in its 0 printing position. Such further clockwise rocking of the pawl I8 places the shoulder I25 on said pawl behind a lateral lug I20 on a link I21 which 15 pivotally connected at its rear end with the upper portion of the latch n for the corresponomg order, and is slldably guided on a rod I28 supported in the side names :5 of the printing mechanism so that, during the latter portion of the forward movement OI the shaft 15 and pawls '78, the link IZI will be moved forwardly to rock the latch H and release the hring member 72 to actuate the printing hammer on in a corresponding order whereby the'$ type positioned at the printing line of the platen is struck agamst the paper to print a 3.

Normalizing safeguard printing means stud I30 (Fig. 3) positioned between the two leftwardly extending lateral lugs III on the rear arm I I0 of the pawl If for the highest order of the safeguard printing control, is carried by one lateralarm of a yoke member I3I pivoted on the shaft I04. A second lateral arm of the yoke I3l extends downwardly behind a stud I32 on the upper arm of a bell crank lever I33 pivoted on a fixed stud I34 and having a forwardlyextending arm the end of which is positioned above the camshaft I35. A pinion I36 fixed on the end of the camshaft I35 meshes with rack teeth on the I upper edge of one end of a slide I31 forwardly and rearwardly movable on fixed studs I38 and I39 supported in the left-hand side plate I5 of the printing mechanism frame and in the end of the shaft 77', respectively. It should be noted that said left-hand side plate I5 has been omitted from Fig. 2 to permit clear illustration of members located between the two plates 75. The slide I31 is urged forwardly to the position of Fig. 2 by a spring I48, referred to hereinafter, to place the shaft in a rotary position where a cam projection I4I. on the shaft I35 elevates the lower forward arm of the bell crank I33 and thus rocks the yoke member I3I clockwise to the position of Fig. 2 where the stud I30 holds the highest order pawl IOI and thus also all of thelower order I pawls; IIII againsti movement: counterclockwise .theslide. I31 remains in its normal forward. position, the lower ends .of the arms. I08 of.the pawls IIII will at..all times. be held. rearwardly of the studs .I 09 .on .the levers whereby the rear .ends of .said levers. will, ineach machineoperation, be permitted. .to move upwardly -at deast. totheir normal printingpositions whereby the safeguard symbolorcharacter type- 100 will always be elevated above the printinglineof the-platen, and whereby also theprinting hammer 60' inany orderstothe left of the highest orderof -the amount to be printed will not be fired, inasmuch as the-rear end of thelever 46 for such order-"will not. be depressed to cause engagement of the shoulder I25-on the pawlflfl for such order with thelug I26 on the corresponding link I2 1, although said lever .45, being-in its 0- printing-position, will prevent engagement 'of the rearward hooked end of the--pawl--18--with the:shoulder'-84 on the corresponding latch. When, however, the-slide I31 is. moved rearwardly to -rotate-the camshaft I35 sufi1cientlyto remove the-cam projection I from beneath the-forwardlower-arm Ofuthfibfill crank I 33, the pawls-I III will be permitted torock-counterclockwise out of their nor- 'mal positions when the shaft Iris-depressed during the machine operation, except-"as suchprinted isautomatic intaccordancewithrthe condition .of. the. means,- including; the .-pawls...I.0I,

- Automaticcontrol ofnormalizing of. safeguard printing control In machines with traveling paper carriages, particularly where checks or other documents on which safeguard printing is to be effected .are

passed around one portion of the platen and business. record sheets are passedaround another portion of theplaten, the condition of ,the safeguard printing control means may be controlled automatically in accordance with the position of the papercarriage, thatis, automatically in accordance with the condition of the columnar printing control means. For thispurpose; a stud "I45on the rear end of the slide I31 is engaged 'by the upper end'of'the *bell' crank lever I46, which is pivoted on ,a-nxed stud I41 on the machine frame and urged clockwise inF'ig. 2 by a spring I48, whereby said spring also urges theslide .I31 forwardly. A short rearwardly extending arm I50 of the lever engages in a slot in one arm I5I (Fig. v1) of a yoke member I52 pivoted on a stud I53 carried by the back plate, of the machine frame. A- second arm I54 of the yoke member ispositioned in the path of travel of one or more control rolls I55 mounted on the paper carriage 51 whereby, in a desired columnar positionor positions of the paper carriage, depending upon the positioning of the roll or rolls I55 on the carriage, the arm I54 will be depressed by a roll I55 to rock the bell crank I46, I50 counterclockwise whereby the:slide I31 will be pulled rearwardly through the spring I 49 which is connected between the arm I and slide I41. Thereby the camshaft I35 is rotated to enable the safeguard printing control means to-cause safeguard printing in machine operations performed when the paper carriage is in any columnar position where the control roll. is=located to depress the arm I54 to therequired extent. To permit the carriage to remain stationary in suchza: columnar position, the carriage tabulating mechanism may be disabled by depression of a Carriage Normal 'key as disclosedin Lundgren'Patent 1,195,599 wherein the Carriage Normal key is numbered I40.

Manual control of safeguard printing control means The condition of the safeguardprinting; control means may alsozbe controlled-manually, this being particularly desirable in some machines,- intended for .only'part-time use'on'work requiring safeguard-:printing and to permit the most convenient-use of the machine at other times for ordinary calculating machine work with normal printing. In the illustrated machine, the stem I of the-upper motor bar U is connected with an arm IEI fixed on a shaft lfiz'journaled in the side platesof the machine frame. A second arm I53 fixed onithe shaft I 62'has its lower end positioned in front of a'stud I64'0n the slide I31 sothat, upon'depression of the upper motor bar, the shaft I 62'is rocked clockwise'and the slide I31. moved rearwardly to place the safeguard printing control means in safeguard printing condition. In the Burroughs High Keyboard machine, as well known, the motor'bars, when depressed to initiate-"machine. operations, are latched in depressedposition through a portion of the machine cycle extending :beyond the point at which the printingxhammers arefired. With the construction'described, safeguard printing will be effected in any machineoperation initiated by depression of the upper motor bar U, whereas regular printing without the printingof safeguard characters or symbols will'beeifectedin any machine operation'initiated by depression of the regular-motor bar, providedthat theslide I31 is not held in a rearward positionby a roll I55.

Variable elimination of. printing in selected groups ,oforders For certain 'types of work it is desirable to eliminate printing in selected groups of orders in selected operations of the machine. One illustration is'given in-Fig. 9, which shows an example of workperformed by the machine in printing in the amount of the gross earnings, the deductions and the net pay of an employee .on the stub of a'paycheck and then printing the amount. of the employeespayon the'pay check; The pay check form used in the example is one having the words Dollars and and the word Cents printed on the check with a space between the words And and Cents so that, in filling in the amount of the check, the dollars portion of the amount is to be printed before the word Dollars and preceded by a safeguard character or symbol, and the cents portion of the amount is to be printed between the words And and Cents, and the entire amount, preceded by a safeguard character or symbol, is to be printed after the word Cents. At the time of printing the dollars portion of the amount before the word Dollars, printing in the dimes and pennies orders is prevented, and at the time of printing in the cents portion of the amount before the word Cents printing in orders higher than the dimes order is prevented. In the illustrated machine this selective printing elimination or so-called hammer block in selected groups of orders is automatically controlled by the paper carriage in accordance with the columnar positions of the carriage.

The slide I31, which, as previously mentioned, is controlled by the rolls I55 on the paper carriage, carries a stud I (Fig. 1) which underlies the rearward arms of two three-armed levers HI and I12 pivoted on the fixed stud 39 and urged counterclockwise into engagement with the stud I10 by springs I13 connected at their rearward ends with the downward arms of said three-armed levers. Each of the levers I1I, I12 has a forwardly extending third arm provided at its end with a downwardly and forwardly inclined cam edge contacting with studs I14 and I15, respectively, carried by the respective ones of two balls I16 and I11, the side arms of both of which are pivotally supported on a pair of studs I18 secured in the side plates 15 of the printing mechanism frame. The springs I13, the rear ends of which are connected to the three-armed levers HI and I12, respectively, are connected at their forward ends to the bails I16 and I11, respectively, above the pivotal axis of said bails to urge the latter counterclockwise to maintain the studs I14 and I15 in contact with the forward arms of the levers HI and I12.

The rear arms of the three-armed levers HI and I12 are formed with notches I8I and I82, respectively, which are so located with reference to the stud I10 on the slide I31 that, when the slide is in the normal forward position which it occupies when no roll I55 on the carriage is in engagement with the arm I54, the stud is engaged by the straight lower edges of the rearward arms of the members Ill and H2 forwardly of both notches I8I and I32, but when the slide I31 is moved one position rearwardly by engagement of the smallest size roll I55 with the arm I54, the stud I10, while still engaging the straight lower edge of the member I12 forwardly of the notch I82, is, however, aligned with the notch I8I in the member I1I, permitting the spring I13 for said lever I1I to rock the latter counterclockwise whereby its forward cam arm, acting on the stud I14, cams the bail I16 clockwise. Thereby, a portion of the rear edge of the cross piece of the bail I16 is moved over the forward ends of the forward arms of the hammer firing members 12 for the pennies and dimes orders of the printing mechanism, whereby printing in the pennies and to interfere with the firing members 12 in those orders in which printing is desired when the paper carriage is in the columnar position where the small roll I55 acts on the arm I54.

When a medium size roll I55 engages the arm I54 to move the slide to its second positionrearwardly of its normal position, the stud I10 moves rearwardly of the notch I8I and cams the threearmed lever il'i clockwise to its normal position of Fig. 1 and is aligned with the notch I82 in the rearward three-armed lever of the member I12, whereby the latter is permitted to be rocked counterclockwise by its spring I13 so that the forward cam end of said member I12, acting on the stud I15, rocks the bail I11 clockwise and positions the rearward edge of the cross piece of. said bail I1! over the forward ends of the forward arms of the hammer firing members 12 in the units of dollars and all higher orders to eliminate printing in those orders. The cross piece of the bail I11 is notched as at I84 so as not to interfere with the operation of the firing members 12 in the pennies and dimes orders whereby, when a medium size roll I55 is positioned over the arm I54, printing is effected only in the pennies and dimes orders.

When the largest size roll I55 is positioned over the arm 554, the slide I31 and stud I10 are moved to a third position rearwardly of their normal positions where the stud I10 engages the straight portion of the lower edge of both threearmed levers HI and I12 rearwardly of both notches I8I and I82 to hold both of said threearmed levers in their normal positions of Fig. 1 to permit printing by all orders of the printing mechanism.

Example of work in the setup of the carriage controls of safeguard printing and printing elimination illustrated in Fig. 9, no control rolls I 55 are provided for the first three columnar positions of the paper carriage where the gross amount of earnings, the deductions and the net amount of earnings, respectively, are printed on the check stub. When the paper carriage is in one of these first three columnar positions, the slide I31, shaft I35 and stud I10 will, therefore, occupy the positions shown in Fig. 1 where the safeguard printing control is disabled by the cam projection I4I raising the lower forward end of the lever I33 and the hammer block bails I15 and I11 are both disabled by reason of the stud I10 being in contact with the under edges of the rear arms of the levers HI and I12 forwardly of both notches NH and I82.

In the fourth columnar position of the carriage where the dollars portion of the amount is to be printed in front of the word Dollars on the check and preceded by a safeguard symbol, a small roll I55 on the carriage depresses the arm I54 to move the slide I31 rearwardly to position the stud I10 in the notch I8! and rotate the shaft I35 a quarter revolution clockwise to remove the cam projection I4I from beneath the forward end of the lever I33, whereby the safeguard printing control is enabled to cause the printing of a :5 immediately tothe left of the highest order of the dollars portion of the amount, but printing of the cents portion of the amount is eliminated.

In the fifth columnar position of the carriage a medium size roll I55 moves the slide I31 further rearward to rotate the shaft I35 another quarter revolution clockwise and move the stud I10. into .the notch .I 82 in the lever-1| "whereby, though thesafeguard printing control means-still remains inactive condition and a type in:.the hundreds of dollars orderwill be indexed at the printing line, printing in ;all orders exceptlthe pennies and dimes orders is. eliminated by the bail ITI whereby only the cents portionof the amount will be printed between .the words And and Cents.

In the sixth columnar position of the'carriage, a large size roll I55moves'theslide I31 still farther rearwardly to rotate the shaft I35:another quarter revolution clockwise where the cam projection I still does notcontactthe lever I33 but leaves the safeguard printing control means active, and where thestud I10 engages'the lower edges of the levers I'll and H2 rearwardly of both notches IN and I82 whereby the entire amount of'thecheck anda immediately to the left of such amount will be printed on thecheck to: theright otthe word Cents."

While the construction above described by way ofjexample only is admirablysuited for the'purposes referred .to, it wilLbe: apparent to those skilled in the art that the construction is susceptible of various modifications which may be found particularly convenient given circumstances. For example, whereas the safeguard printing control means .in the construction illustrated and describedabove is normally in a disabled or nor- 3.

malized condition but may be placed in an effective safeguard printin condition by either manual or automatic control, or both, that may be reversed so-thatthe safeguard printing control means is normally in a'safeguard printing condimeshing the pinion I36 on said shaft from the rack .on the slide I31 and rotating said shaft I35 to the required extent before remeshing the pinion I36 with the rack. Also, instead of effecting the manual control of the condition of the safeguard -printing control means by means of a motor bar for single operations initiated bydepression .of-suoh motor bar, the-position of the slide I 31 and thereby the condition of the safeguard printing control means may easily be controlled by a manipulative member releasably latchable in any of its positions of adjustment.

The particular form and arrangement of-the safeguard printing control members illustrated in Figs. 3 to 7 is especially well suited for use in work involving different systems of currency. In the accompanying drawings the mechanism has been illustrated as used for safeguard printing of amounts in a decimal currency, specifically United States currency, althoughit will be-apparent that, by the mere substitution ofother appropriate safeguard character types for the 3 types, the machine may be used for printing amounts in other decimal currencies. It is to be noted, also, that the same mechanism may be used for printing amountsin a nondecimal ourrency, specifically English currency, by merely replacing the type 100 in the third lowest order by a type and by placing a on each of the type 55 in the lowest order and in the third lowest order, as well as-by replacing the is type 100 in the fourth and fifth orders by type bearing the English pound-r symbol After such changes of type the-machine will print, for examples, theamount of-oneapound five shillings as-..l.05 and fifteene shillingsas -.-.15f.
